Jason, there are groups around your area. Metroplex atheists and Dallas Plano atheists can be found on meetup. There's also Frisco atheists which can be found on Facebook. There are more groups, these are just off the top of my head. You are definitely of alone.

Not sure, but I think I am the only atheist in Texas. If I am not, the others are all too scared to talk!! This is not my first "babble belt" state as I have lived in Georgia and NW Florida (hell on earth). NW Florida is proof alone that if there is a god he screwed up really bad! haha

Last week, my company went through a dramatic series of cuts, firing over 600 people in one day. I'm the only out atheist in my department, and out of 75 people in the department, I was chosen as one of the 30 to carry on having a job. I should also mention that I'm deep in the Bible Belt, in Mobile, Alabama. I post this just so you know, being "out" as an atheist isn't necessarily the kiss of death for your job. Sometimes the powers that be can look beyond politics and religion and just pick the person most qualified for the position.
